Same size different make and year here. I don't have a ford but I do have a 2011 and a 2012 Rams that are 4500s they are both crew cabs. So the gvw for us was 16000 now the reg cab it can be 16500 so higher gvw with a lower weight cab since its obviously smaller. Anyways in our case the trucks weighed about 8200 before the beds and with the beds close to 9300. Meaning we could carry 6700 pounds.
